Regarding the image of the number one need not go to the men in black for assistance. If you are operating a MS based OS you have a little gem of a program named MS Paint.
Copy the image you wish to have an enlargement of, or a portion of and copy/paste it to Paint. You can use the Stretch/Skew tool at the top of the screen toolbar to enlarge the image or a portion of it. What you gain in size loses definition, you will be dealing with an undecernable mass of pixels at some point in the process. Copy the image of the USS Petrel to MS Paint and give the tool a try.
